Abstract (en)
A means for defibrating and sorting pulp in paper and cellulose industry, comprising a defibrating means (1,2) consisting of a rotor (2) and a stator (1), wherebetween is established a defibrating zone, and of a sorter (2,3) consisting of the same rotor (2) and another stator (3), wherebetween is established a sorting zone, and said stator (3) of the sorter is formed to be sieve-like, and said means comprising a pulp feed (4), accept removal (7) and reject removal (6). At present, defibrating and sorting processes have to be carried out using separate apparatus, which is expensive and space-consuming. With the aid of the present invention, the problem is solved in that the angle ( alpha ) between the centre-line (8) of the shaft of the rotor (2) and the defibrating zone is 75 to 105 DEG and the angel ( beta ) between the sorting zone and the centre-line (8) of the shaft of the rotor (2) is 75 to 105 DEG , and that the defibrating zone and the sorting zone are located in the same pulp space (5).
